This invention relates to improvements in flat irons which comprise self-contained heating units, preferably electrical, and are provided with means for emitting live steam through the face of the iron to the fabric being ironed. The invention comprises means for supplying steam to the iron and certain passages and chambers for the steam within the base or body of the iron with vents opening through the bottom or sole of the iron, and means associated with the said chambers to provide substantial steam expansion within the body of the iron between the source of steam supply and the vent passages, such associated means serving to trap any condensation of the steam that may occur.

An object of the invention is to provide combined and associ-ated means for preventing the emission of water with the steam upon or into the material being ironed.

With the foregoing object and others which may hereinafter appear, the invention consists of the novel construction, combination and arrangement of parts as will be further referred to and illustrated in the accompanying drawings wherein is shown a preferred embodiment of the invention, but it is to be understood that changes, variations and modifications may be resorted to which fall within the scope of the invention as claimed.

In the drawings:

Fig. 1 is a side elevation and partial longitudinal section of an iron taken on line I I of Fig. 2 embodying the invention, and showing accessories for supplying the heating current and steam;

Fig. 2 is a horizontal section on line 2 2 of Fig. 1;

Fig".VA 3 is a longitudinal vvertical section of the body of the iron on line 3--3 'of Fig. 2;'

Fig. 4 is a transverse vertical section on line 4 4 of Fig. 2;

Fig. 5 is a similar section on line 5 5 of Fig. 2;

Fig. 6 is a vertical section of the body on line 6 6 of Fig. 2;

Fig. 7 is a similar section on line 'I 'I of Fig. 2, and

Fig. 8 is a transverse vertical section on line 8-8 of Fig. 2.

Formed in the rear or heel portion of the base member I is a wide steam receiving chamber 2 disposed between the rear wall 3 of the casting and an integral partition wall 4 which extends from side to side of the interior of the body and is furnished at its center upper part with an aperture 5 which terminates at its forward end in 4 Claims. (Cl. 38-77) a constricted portion 6 of smaller diameter. This chamber communicates with a steam passage I in a steam fitting 8 to which a suitable steam hose may be attached. As shown in Fig. 2 a pipe threaded and tapped hole II is provided in the rear wall of the iron in suitable alignment with the aperture 5 to facilitate the drilling of the latter. This hole and other suitable openings, if desired, may be employed for the removal of core sand from the interior of the casting. The

opening II eventually will be tightly stopped by means of any suitable pipe plug in a well known manner.

Forwardly of the wall 4 a central chamber I3 is formed and is disposed between the said wall 4 and a pair of inwardly extending baille Walls I2. This chamber occupies the full Width of the interior of the iron at this point and connects centrally with a chamber I4 located in the front or toe of the body. The communication between the central and toe chambers is made through the passage I6 between the inner ends of bai'lles I2, and, as shown, is of approximately the 'same transverse width as the similar dimension of each of the bailles I2. A baiile wall I5 extends transversely across the steam chamber I3 into a suitable closeness to the internal side walls of the iron to provide a pair of lateral steam passages i'I. A longitudinally extending baille wall I8 occupies the central portion of the chamber I4 and serves to divide the steam entering the chamber I4 and disperse it against and over the inner walls I9 of a pair of forwardly joining ledges 2u which extend inwardly from the sides of the iron in this region of the base. Steam passing over the ledges 20 yis then carried from the shallow spaces `2.2 to andv through the sole of the iron by means of a plurality of apertures 2|v drilled through the ledges 20, as indicated in the drawings. y

I Mounted on top of the base member I is the electrical heating unit 23, of any preferred type, provided with the usual thermostatic control and which is'held in position by means of afclamp plate 24 and Astud assembly 25. Thelll'ting unit is provided as usual with terminal posts 26 which are adapted to receive a socket of known construction carried at the end of an electrical supply conduit 28. A shaped sheet metal cover 29 is secured to the clamp plate 24 by suitable screws (not shown) and a suitable handle 30 is also secured to the clamp plate, as by means of studs 3|.

Any suitable flexible steam conduit may be attached to the member 8 to bring steam from
